Document Summary
Life relies on enzymes that speed up rates of chemical reactions: no need to increase temperature, key role of enzymes, growth, reproduction, movement, ability to respond to stimuli. 3. 1 energy and the laws of thermodynamics: energy: capacity to do work. 3. 1b the laws of thermodynamics describes energy and its transformation: thermodynamics: study of energy flow in chemical and physical reaction, system: object being studied, surrounding: everything outside the system. Isolated system: does no exchange energy or matter: ex: thermos bottle, closed system: can exchange energy but no matter, ex: sauce pan with lid, open system: can exchange energy and matter, ex: ocean -> absorbs and releases energy. 3. 1c the first law of thermodynamics: energy can be transformed but not created or. Destroyed: first law of thermodynamics: energy cannot be created or destroyed, but it can be transformed, ex: niagara falls, pe -> ke -> heat, sound, and me.
